Inventor: ISREAL CHARLES M
IPC: H04L12/00
Filed: 1987-02-25
Granted: 1990-05-08
Abstract: - 27 -AN INTERFACE CIRCUIT FOR INTERCONNECTING CIRCUIT SWITCHED AND PACKET SWITCHED SYSTEMS Abstract An interface circuit is described for interconnecting a packet switched system to a circuit switched system which enables a uniform dialing plan to be utilized to establish intra-system or inter-system connections. This is accomplished by assigning each terminal of the packet switched system a unique terminal address similar to the extension number used for terminals of the circuit switched system. The interface also distinguishes data call set-up requests from other control commands received from the packet switched system.

Title: Annular extrusion die with internal choke ring and spider mandrel
Inventor: GROSS JONATHAN
IPC: B29C48/10
Filed: 1987-03-13
Granted: 1990-09-18
Abstract: ABSTRACT OF THE DISCLOSURE An annular extrusion die for extruding tubular thermoplastic materials, such as foamed thermoplastic, which incorporates an internal spider mandrel and a novel choke ring for eliminating striations in the extruded thermoplastic material while Imparting an improved control over the uniformity in the gauge or thickness of the extruded plastic material. In order to more accurately control the uniformity in the gauge of the extruded plastic material; rather than varying the width of the gap or restriction in the die flow passageway formed by the choke ring which, in response to even minor changes in the gap width considerably changes the flow quantity, may overcompensate or overcontrol variations in the gauge thickness; there is varied the length of the land of the choke ring in the direction of material flow, in effect, in the machine direction, downstream of the spiders supporting the internal mandrel.

Abstract: ABSTRACT    A screen placement apparatus and system wherein the apparatus includes a motor for providing rotational torque to an auger received within a ground screen and a disposable cutting tip having a cutting diameter equal to or greater than the outer diameter of the screen is connected to the end of the auger.  The screen is placed into the ground by simultaneously drilling the hole with the disposable cutting tip, drawing the drill cuttings up through the screen with the auger, and inserting the screen into the hole.  The drill cuttings, drawn up through the hole, are discharged through discharge openings.  After the desired depth is reached, the auger and motor are longitudinally moved with respect to the screen and cutting tip thereby permanently disconnecting the disposable cutting tip and leaving it within the ground.  The auger is, thereafter, retracted from within the ground screen.  In an alternate embodiment, a retractable cutting bit is provided for drilling a hole of equal or greater diameter than the screen and, thereafter, being retracted up through the screen along with the auger.          A plug is provided for plugging the screen at a desired depth.

Abstract: ABSTRACT:          Radiation-sensitive semiconductor device.     A radiation sensitive semiconductor device comprising a high-ohmic semiconductor wafer having a thicker edge portion (1A) and a thinner central portion (1B), in which a photodiode (5) is located. The surface opposite to the photodiode is provided with a highly doped contact layer (7), on which a metal layer (8) is provided. The central portion is so thin that at a low photodiode voltage the depletion zone of the photodiode extends as far as the contact layer (7). According to the invention, the device comprises an active screening diode (11), which extends both in the edge portion and in the central portion and whose depletion zone extends in the operating condition in the central portion also as far as the contact layer (7). As a result, diffusion of charge carriers from the edge portion to the photodiode is avoided.            Fig.  .
